This, of course, is conducive to economical manufacture of the retaining means.

The spring utilized in conjunction with rod 6 may take other forms, for instance, those shown in Figs. 5 and 6 or Fig. 7. The type shown in Figs. 5 and 6 comprises an arched spring ll having cross-like legs or terminations I2. Similar to spring H], spring I I is preferably loosely mounted upon rod 6, the arched portion of the spring being adapted to bear upon the head 9 and the legs I2 bearing upon the outer face of the dished plate. The function and cooperation of this type spring is similar in all other respects to spring I 0. The type shown in Fig. '7 is a frustro-conical coil type [3, the spring being confined between head 9 and the outer face of plate 4. Similar tosprings i8 and H, spring I3 is preferably loosely mounted upon rods 6 and is removable therefrom at the opposite end of the rod. It is to be understood, however, that it is within the contemplation of my invention to have springs in, II and I3 integrally secured to one end of each of the rods 6.

I claim as my invention:

1. A roll end protector comprising in combination, a pair of plates to be positioned at opposite ends of the roll, and means for maintaining said plates in resilient contact with the ends of said roll comprising, a rod which extends through the center of the roll, the ends of said rod normally projecting through said plates, a head on one end of said rod, a resilient member mounted on said rod and confined between said head and the surface of a plate, and means at the opposite projecting end of said rod for preventing movement of said rod inwardly with respect to the opposite plate.

2. A roll end protector comprising in combination, a pair of plates to be positioned at opposite ends of the roll, and means for maintaining said plates in resilient contact with the ends of said roll comprising, a rod which extends through the center of the roll, the ends of said rod normally projecting through said plates, a head on one end of said rod, a spring loosely mounted on said rod and confined between said head and the surface of a plate, and means at the opposite projecting end of said rod for preventing movement of said rod inwardly with respect to the opposite plate.

3. A roll end protector comprising in combination, a pair of plates to be positioned at opposite ends of the roll, and means for maintaining said plates in resilient contact with the ends of said roll comprising, a rod which extends through the center of the roll, the ends of said rod normally projecting through said plates, at head on one end of said rod, an arched blade spring mounted on said rod and confined between said head and the surface of a plate, and means at the opposite projecting end of said rod for preventing movement of said rod inwardly with respect to the opposite plate.

4. A roll end protector comprising in combination, a pair of plates to be positioned at opposite ends of the roll, and means for maintaining said plates in resilient contact with the ends of said roll comprising, a rod which extends through the center of the roll, the ends of said rod normally projecting through said plates, a head on one end of said rod, a coil spring mounted on said rod and confined between said head and the surface of a plate, and means at the opposite projecting end of said rod for preventing movement of said rod inwardly with respect to the opposite plate.

5. A roll end protector comprising in combination, a pair of plates to be positioned at opposite ends of the roll, and means for maintaining said plates in resilient contact with the ends of said roll comprising, a rod which extends through the center of the roll, said roll being of greater length than the distance between said plates, the ends of said rod normally projecting through said plates, a head on one end of said rod, a resilient member loosely mounted on said rod and confined between said head and the surface of a plate, and means at the opposite projecting end of said rod for preventing movement of said rod inwardly with respect to the opposite plate.

6. A roll end protector comprising in combination, a pair of plates to be positioned at opposite ends of the roll, and means for maintaining said plates in resilient contact with the ends of said roll comprising, a rod which extends thrcugh the center of the roll, the ends of said rod normally projecting through said plates, a head on one end of said rod, a coil spring mounted on said rod and confined between said head and the surface of a plate, said spring being frustro-conical in form having the small end positioned for engaging the underside of said head of the rod and the larger end engaging said plate, and means at the opposite projecting end of said rod for preventing movement of said rod inwardly with respect to the opposite plate.
